As 'lawful espials' is only in the folio, injures the measure, and is not necessary, I would omit it.
"Or to take arms against a sea of troubles."
Though we meet in Shakespeare with incongruities as great as this, I incline to read for 'sea' siege, my own conjecture, as well as Pope's. We have "All sores lay siege" (Tim. iv. 3), "Sickness did lay siege" (M. N. D. i. 1), and several other expressions; and this is almost a solitary instance of the figurative use of 'sea' by our poet. Assay, or assays, for 'a sea,' has also been proposed, "Galling the gleaned land with hot assays" (Hen. V. i. 2); and it may have been the poet's word. If so, I should incline to read the assay.
"With a bare bodkin? Who would these fardels bear."
This is the reading of the folio, which I retain. 'These,' which gives much force to the expression, refers either to the evils he had enumerated, or is, as is so frequently the case, used in a general indefinite sense.
"In the undiscover'd country from whose bourne
No traveller returns."
